Delays in patients suspected of acute coronary syndrome (ACS) should be kept as short as possible to reduce complications and mortality. In this review we discuss the substantial pre-hospital delays of ST-elevated myocardial infarction (STEMI) patients as well as non-STEMI patients. The pre-hospital delays include patient, doctor and emergency medical transport (EMT) delay. Patient delay is among the longest in the pre-hospital chain of ACS patients. Interventions as mass media campaigns or individual education programs have not yet shown much improvement. Patients with chest pain most often contact the general practitioner (GP) instead of the recommended EMT, increasing delays as well. To decrease the delays by referring all patients promptly and without restriction to the emergency department (ED) is not feasible. Up to 80% of the patients with chest pain do not have a cardiac diagnosis and thus referral of all these patients would result in overcrowding of the ED. Triage is therefore crucial. Triage of patients with chest pain is therefore imperative and there is a great need of (validated) triage tools.
